Mixing machine with wedge-shaped or ploughshare-like mixing tools

摘要

An impeller-type mixing machine is provided with movable wedge-shaped or ploughshare shaped mixing tools. Each tool has a tip running upstream and lateral cheeks emanating from it and acting as working surfaces. At least one of the cheeks is placed obliquely to the direction of movement of the mixing tools. The cheeks of each mixing tool run at an obtuse angle to the longitudinal axis thereof.
